How do I report the stage in which a declarative pipeline failed? In the fail block, I want to get failedStage.name and report it (eventually to slack).

pip

    PipelineVisitor is a fine approach. However, if you want to see just the errors, then leveraging FlowGraphTable might be even better.

    The following provides a list of maps for each failed steps, and traverses the downstream jobs as well. I find it to be pretty useful.

    You'll want to use a shared library to avoid the security sandbox warnings / approvals

    List getStepResults() {
    def result = []
    WorkflowRun build = currentBuild()
    FlowGraphTable t = new FlowGraphTable(build.execution)
    t.build()
    for (def row in t.rows) {
        if (row.node.error) {
            def nodeInfo = [
                    'name': "${row.node.displayName}",
                    'url': "${env.JENKINS_URL}${row.node.url}",
                    'error': "${row.node.error.error}",
                    'downstream': [:]

            ]
            if (row.node.getAction(LogStorageAction)) {
                nodeInfo.url += 'log/'
            }

            for (def entry in getDownStreamJobAndBuildNumber(row.node)) {
                nodeInfo.downstream["${entry.key}-${entry.value}"] = getStepResults(entry.key, entry.value)
            }
            result << nodeInfo
        }
    }
    log(result)
    return result
}

Map getDownStreamJobAndBuildNumber(def node) {
    Map downStreamJobsAndBuilds = [:]
    for (def action in node.getActions(NodeDownstreamBuildAction)) {
        def result = (action.link =~ /.*\/(?!\/)(.*)\/runs\/(.*)\//).findAll()
        if (result) {
            downStreamJobsAndBuilds[result[0][1]] = result[0][2]
        }
    }
    return downStreamJobsAndBuilds
}
